What Saunders International does

Saunders International Limited (ASX: SND) is an Australian, ASX-listed multidisciplinary engineering, construction and industrial asset services company headquartered in Rhodes, New South Wales, founded in 1951 and operating with 580+ professionals across 11 Australian offices plus operations in Papua New Guinea and New Zealand. The company delivers five integrated service capabilities: fluid storage and transfer infrastructure (including its proprietary tank jacking top-down construction method), structural, mechanical and piping (SMP) fabrication and installation from a Queensland workshop, industrial automation and electrical (OT/IT integration, OT cybersecurity, control system design, machine learning and process optimisation), civil and water infrastructure (bridges, marine works, pipelines, pump stations, treatment plants and reservoirs through Saunders Aqua Metro), and recurring industrial asset and maintenance services spanning inspection, repair, modification, shutdowns and decommissioning.

Saunders serves four primary vertical markets — Defence & Government, Water, Energy, and Resources & Industrials — with named blue-chip and government clients including the Australian Department of Defence and NAVFAC Pacific (RAAF Bases Tindal, Learmonth, Larrakeyah, Stirling), Ampol (Lytton Refinery, Future Fuels Desulphurisation), Mobil (Altona terminal five-year maintenance programme), Northern Star Resources / KCGM, CleanCo Queensland, Greater Western Water, Veolia, Quantem, Edith Cowan University, and tier-one contractors such as CPB Contractors, Laing O'Rourke and Multiplex. Disclosed contract values for major projects range from approximately $10M to $20M, with delivery typically spanning 12–24 months.

The business model blends one-time EPC and construction project revenue ($10M–$20M+ per project) with annuity-style recurring revenue from multi-year maintenance programmes and Master Services Agreements (notably with Ampol and Mobil), and operates as a direct-to-enterprise and direct-to-government provider via project-based contracting rather than channel or partner-led distribution. The portfolio has been actively reshaped through five acquisitions since 2017 — Civilbuild (2017), PlantWeave (2021), Automation IT and Piping Solutions (2023), and Aqua Metro (2025, forming Saunders Aqua Metro) — extending the company from a single-sector tank specialist into a multi-disciplinary platform with automation, civil, water and process infrastructure capabilities.

Direct peers

• SRG Global: ASX-listed specialist engineering, construction and maintenance services firm of comparable size, similarly diversified across resources, energy, infrastructure and defence-adjacent work in Australia.

• McConnell Dowell: Australian-headquartered EPC contractor delivering pipelines, water infrastructure, tanks and marine structures across Australasia — directly overlapping with Saunders' SMP, water and tank construction capabilities.
• Monadelphous Group: ASX-listed engineering and maintenance services group serving resources, energy and infrastructure in Australia. Highly comparable to Saunders in size, service mix (EPC + maintenance) and customer overlap in mining and industrial markets.
• Sedgman (CIMIC Group): Specialist mineral processing EPC contractor delivering tank construction, process plant design and construction for mining customers — directly comparable to Saunders' Resources & Industrials tank and process infrastructure work.

Broad incumbents

• Downer EDI: One of Australia's largest infrastructure services groups with overlapping water, rail, energy and asset maintenance businesses, but operating at materially greater scale and breadth than Saunders.
• CPB Contractors (CIMIC Group): Major Australian construction contractor that acts both as a competitor for large infrastructure tenders and as a prime contractor engaging Saunders as subcontractor on defence fuel projects. Same end markets and customer base.
• John Holland (CPB Contractors): Major Australian construction contractor delivering transport, water and infrastructure projects — overlapping with Saunders' civil and water infrastructure capability but at a larger scale.
• UGL (CIMIC Group): Australian engineering and asset services firm delivering maintenance, fabrication and construction across rail, resources, water and defence — directly comparable to Saunders' multidisciplinary EPC plus maintenance model.
• Ventia Services Group: Large ASX-listed infrastructure services firm providing maintenance, asset management and operations support across defence, water and energy — Saunders' CEO and several executives came from Ventia, reinforcing the comparability.
